Hi Folks,
I see many XML instances (and corresponding XML Schemas) with an "other" catchall element.
I wish to convince you that an "other" catchall element is contrary to one's objectives and should be avoided.

Roger - there is a tradeoff to everything. If you force people to
choose among categories that don't fit, they may just walk away. I
can't count the number of surveys I have declined to fill out for that
reason.
